Question

What is the slope of the line that passes through the points (-9,-3) and (1,-3)​

Answer 1

Explanation:

(
`x_(1)` ,
`y_(1)` )

(
`x_(2)` ,
`y_(2)` )

m =
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`

~~~~~~~~~~~~

( - 9 , - 3 )

( 1 , - 3 )

m =
`(-3+(-3))/(-9-1)` =
`(0)/(-10)` = 0 , line is horizontal
